So you believe "God" is the singularity
That exact description is more in line with your beliefs. For those born again, they have passed beyond mere belief in the matter of the existence of God. The believer still believes in the promises of God and has faith in the ultimate goodness of God, but belief concerning their position with God and especially his existence, is no longer an issue. It is an irrefutable knowing.
The Spirit itself beareth witness with our spirit , that we are the children of God :- Rom. 8:16
If a person has not this internal witness, he is not of God.
The Singularity that you speak of is the author of LIFE and offers it as a free gift to all who ask for it . Once it is granted, some of the substance of that Singularity resides inside the believer and is an internal witness, bearing truth and proof of his existence as well as confirmation for the continued life of the believer.
As Jehovah's Witnesses we were forbidden to ask the Singularity to be born again, being taught that was only for the elite (144,000). What I am quite seriously declaring to you here and now is that LIFE is available for the taking.... for "whosoever".
ye have not , because ye ask not . - James 4: 2
